Dark Winds Finale Sneak Peek: It's Danger On A Train As Leaphorn & Co. Hunt Reynolds (Exclusive)

Leaphorn and Chee may be taking an unplanned trip to Reno, as Dark Winds brings Season 3 to a thrilling close this Sunday at 9/8c.

When last we tuned into the acclaimed AMC/AMC+ period drama, Navajo tribal police Lt. Joe Leaphorn (played by TVLine Performer of the Week Zahn McClarnon) came to realize that archeologist Dr. Reynolds (Christopher Heyerdahl) had been seeding his dig site with artifact fragments. Reynolds had in turn killed Ernesto and now is hunting George Bowlegs, after the kids stumbled across his handiwork late one night.

Having revisited George's campsite anew in the light of day, Leaphorn and deputy Jim Chee (Kiowa Gordon) know where George is headed — to the train station, to catch a ride to Reno. Alas, Reynolds spied the same piece of train schedule.

The race is now on, as seen in the exclusive sneak peek above, for a plain-clothed Leaphorn, Chee, Sena (A Martinez) and Bluehouse (Natalie Benally) to track down a dodgy George at the station, before a murderous Reynolds does same. Press play above to get a first taste of the season-ending tension!

Elsewhere in the Season 3 finale, titled "Béésh Łį́į́ (Iron Horse)," Bernadette (Jessica Matten) fights for her life after coming face-to-face with the truth that Tom Spenser (Bruce Greenwood) is trafficking people as well as drugs, and that Garza (Tonantzin Carmelo) — as well as Chief Henry (Terry Serpico) and Ivan (Alex Meraz) — have been helping to cover the businessman's tracks.
